METAL WEATHER-STRIP.

Specification of Letters Patent.

Patented Sept. 8, 1914.

Application filed February 24, 1913. Serial No. 750,358.

To all whom it may concern:

Be it known that I, JAMns Aon l/VHITTE- MORE, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented a new and useful Meta-l Weather-Strip, of which the following is a specification.

The present invention appertains to weather strips for windows, and particularly to those adapted to be fitted between the jambs of a window and the stiles of the sash.

It is the object of the present invention to provide a novel and improved weather strip of simple and inexpensive construction, the parts of which are attachable to the jamb and sash stile so as to fit snugly therebetween and in order to occupy the minimum of space and to also reduce to a minimum the necessary cutting away of the wood.

The present invention also aims to provide a weather strip which shall be adjustable or flexible to take up any shrinkage of the sash, or to fill up the gap between the stile and the jamb, should any occur, the result being that the weather strip forms provide a weather tight strip and also permits of the application of the weather strip g for the unavoidable shrinkage of the wood.

Vith the foregoing general objects outlined and with other objects in view, which will appear as the nature of the invention is better understood, the present invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein 2* Figure l is a sectional view of a fragmental portion of a window. Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1. Fig. 3 is a view similar to Fig. 1 showing a gap or space provided between the stile of the sash and the jamb, and showing said weather strip closing said gap.

Referring specifically to the drawing, the numeral 4 designates the jamb of the window casing rabbet 9 is bearing the usual parting strip 5 and the stop 6 forming a sash way in which the stile 7 of the sash is movable. The said details are common in window structures and need not be further described, it being understood that the invention is particularly applicable to the construction disclosed, although it is applicable to various modifications thereof.

In carrying out the present invention, the stile 7 is provided with a primary rabbet 8 in its corner adjoining the parting strip 5 and with a relatively shallow and wide secondary rabbet 9 adjoining the parting strip, the rabbets being all the cutting away that is necessary. The rabbets may be readily provided and avoid the usual channel cut in the stile to receive the tongue of a strip secured to the j amb.

The present device of attachment embodies two strips 10 thin sheet metal of suitable gage and qualipreferably employed. also tial The strips should possess the requisite flexibility essento the present invention.

The strip 10 is relatively wide and is attachable at one edge being the stop 6 and the jamb, so that the body and free edge of the strip is disposed snugly between the stile and jamb. The aforesaid edge of the said channel is preferably secured to the j amb by means of nails, tacks or other securing members 12. The strip 10 is provided with an oflset or deflected portion adjoining its free edge, the said offset portion fitting within the rabbet 8 of the stile, and the free edge the oifset portion 13. r

The other strip, designated 11, is angular in cross section, one flange being adapted to flt in the rabbet 9 of the stile, and the other flange 15 being adapted to overlap the refleXed edge 14;, so as to fit snugly between the said refleXed edge and the jamb. The edge 16 of the flange 15 is refleXed or bent back toward the sash so as to interlock slidably with the refleXed edge 14 of the strip 10. The flange which fits in the secondary preferably secured to the stile by nails, tacks or other securing memso that the said flange means of hers 17 the jamb, the said is disposed of weather strips. directed to the fact mately 12 turns or angles in the passage leading from one side of the sash to the other between the stile and jamb, so that a perfect assurance against the passage of air, moisture or the like between the sash and jamb is provided.

What is claimed as new is In combination with a window jainb, and a sash, the stile of the sash having a rabbet; a strip having one edge secured to the jamb and having an offset portion at its free edge fitting in the rabbet, the free edge of the strip being reflexed toward the jamb, and an angle strip having one flange secured to the face of the stile of the sash and having its other flange overlapping the aforesaid refiexed edge, the edge of the latter flange being reflexed toward the sash to interlock slidably with the aforesaid refiexed edge within the rabbet.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.

snugly between the stile and the parting Particular attention is strip 5.

lt is evident from the foregoing, that the strips are concealed, except, perhaps, the outer edges of the sarips. It will also be noted that the free edges of the strips are interlitted or interlocked in a peculiar or novel manner within the rabbet 8 of the stile. The strips may be readily applied to the window with but little difficulty, if any, and they present a perfect barrier to the elements so as to provide a weather tight strip, excluding the ingress or egress of air, moisture, or the like. The strips not only occupy a minimum of space but also require a minimum cutting away of the wood, and it will be noted that the strip 10 is adapted to lien or take up any shrinkage of the stile, or to ill up the gap between the stile and jainb when such a gap occurs. Thus as depicted in Fig. 3, when the sash stile 7 leaves the jarnb i, the free edge of the strip end will be carried with the stile, and the strip 10 will thus e'ltlectively close the gap between the stile and jainl. As a consequence, the present weather strip may be fitted to new windows or to new wood, it not being necessary to wait for the unavoidable shrinkage of the wood, which is necessary with most types M Gopies of this patent may be obtained for five cents each, by addressing the Commissioner of .Eatcnts,
